Abstract (en)
The invention concerns a LNT catalyst for a NO x storage catalyst comprising a platinum group metal component and a metal oxide component, wherein the metal oxide component contains exclusively praseodymium oxide (Pr 6 O 11 ) or praseodymium-lanthanum oxide. The invention further concerns a process for the production of a LNT catalyst comprising a platinum group metal component and a metal oxide component, wherein high-temperature calcination of the metal oxide component is effected prior to addition of the platinum group metal component.
